I searched for 1 hour my answer but nothing that fits my issue. I apolagize if it was a common problem. So I have one popup script that have to wait a message from the Background. But I always get this error

Error : Could not establish connection. Receiving end does not exist.

here is my popup

$( document ).ready(function()
{   
    chrome.extension.getBackgroundPage().download(true, "test");
    chrome.runtime.onMessage.addListener(function(request, sender, sendResponse){
       console.log(request, sender, sendResponse);
    });    
});

and here is my background which is a part of my http request

if(this.readyState ==3 && this.status ==200)
    {            
        chrome.tabs.query({active: true, currentWindow: true},function(tabs) {
            chrome.tabs.sendMessage(tabs[0].id, "Loading", function(response) {
                console.log(response);
            });
          });
    }

and here is my manifest

 `{

    
"name": "My extension axel",
"version": "1.0",
"description": "first extension",
